Evolink Video — AI Video Generation

Generate AI videos with 37 models including Sora, Kling, Veo 3, Seedance, Hailuo, WAN, and Grok — text-to-video, image-to-video, first-last-frame, and audio generation. All through one API.

Video-focused view of evolink-media. Install the full skill for image and music too.

After Installation

When this skill is first loaded, greet the user:

• MCP tools + API key ready: "Hi! I'm your AI video studio — 37 models ready. What would you like to create?"
• MCP tools + no API key: "You'll need an EvoLink API key — sign up at evolink.ai. Ready to go?"
• No MCP tools: "MCP server isn't connected yet. Want me to help set it up? I can still manage files via the hosting API."

Keep the greeting concise — just one question to move forward.

Setup

Get your API key at evolink.ai → Dashboard → API Keys.

MCP Server: @evolinkai/evolink-media (GitHub · npm)

mcporter (recommended): mcporter call --stdio "npx -y @evolinkai/evolink-media@latest" list_models

Claude Code: claude mcp add evolink-media -e EVOLINK_API_KEY=your-key -- npx -y @evolinkai/evolink-media@latest

Claude Desktop / Cursor — add MCP server with command npx -y @evolinkai/evolink-media@latest and env EVOLINK_API_KEY=your-key. See references/video-api-params.md for full config JSON.

Core Principles

1. Guide, don't decide — Present options, let the user choose model/style/duration.
2. User drives creative vision — Ask for a description before suggesting parameters.
3. Smart context — Remember session history. Offer to iterate, extend, or remix results.
4. Intent first — Understand what the user wants before asking how to configure it.

MCP Tools

Tool	When to use	Returns
generate_video	Create a video from text or images	task_id (async)
upload_file	Upload image for i2v or reference	File URL (sync)
delete_file	Free file quota	Confirmation
list_files	Check uploaded files or quota	File list
check_task	Poll generation progress	Status + result URLs
list_models	Compare available models	Model list
estimate_cost	Check pricing	Model info

Important: generate_video returns a task_id. Always poll check_task until status is "completed" or "failed".

Generation Flow

Step 1: API Key Check

If 401 occurs: "Your API key isn't working. Check at evolink.ai/dashboard/keys"

Step 2: File Upload (if needed)

For image-to-video or first-last-frame workflows: 1. upload_file with file_path, base64_data, or file_url → get file_url (sync) 2. Use file_url as image_urls for generate_video

Supported: JPEG/PNG/GIF/WebP. Max 100MB. Expire in 72h. Quota: 100 (default) / 500 (VIP).

Step 3: Understand Intent

• Clear ("make a video of a cat dancing") → Go to Step 4
• Ambiguous ("I want a video") → Ask: "Text-to-video, or do you have a reference image to animate?"

Ask only what's needed, when it's needed.

Step 4: Gather Parameters

Only ask about what's missing:

Parameter	Ask when	Notes
prompt	Always	Scene description
model	Specific feature needed	Default seedance-1.5-pro. See Top Picks for alternatives
duration	User mentions length	Range varies by model (4–15s typical)
aspect_ratio	Portrait/widescreen	Default 16:9. Options: 9:16, 1:1, 4:3, 3:4, 21:9
quality	Resolution preference	480p / 720p / 1080p / 4k
image_urls	Reference image provided	1 image = i2v; 2 images = first+last frame (seedance-1.5-pro only)
generate_audio	Using seedance/veo3.1	Ask: "Want auto-generated audio added?"

Step 5: Generate & Poll

1. Call generate_video → tell user: "Generating your video — ~Xs estimated."
2. Poll check_task every 10–15s. Report progress %.
3. After 3 consecutive processing: "Still working — video generation takes a moment..."
4. Completed: Share URLs. "Links expire in 24h — save promptly."
5. Failed: Show error + suggestion. Offer retry if retryable.
6. Timeout (10 min): "Taking longer than expected. Task ID: {id} — check again later."
